If I understand the question, it sounds like you want to write a method in JavaScript in your HTML, and have it be executed when a worker is created? Do you want it to run in the HTML (on the main thread) or in the worker?
If in HTML, then you can modify the code that creates workers (not sure where, but looking for new Worker() in src/ should find it). Or, you might just patch Worker itself in the main scope, replace it with another method that wraps around it. Overall I don't think we have a nice way to do that right now. If in the worker, then you can't directly do that - functions can't be passed from workers, only JSON-type data.
